Abstract

An apparatus includes a catheter, an introducer having a first member and a second member, a locking mechanism coupled to a distal end of the first member and configured to couple the introducer to a peripheral intravenous line, and an actuator coupled to the catheter. The actuator is configured to move from a first configuration, in which the catheter is disposed within the introducer, toward a second configuration to move the second member to a distal position relative to the first member. A portion of a guide of the second member being distal to the first member when the second member is in the distal position. The actuator is configured to move relative to the second member to be placed in the second configuration when the second member is in its distal position such that the catheter is disposed within and extending past an end of the peripheral intravenous line.

Claims (11)

1 . An apparatus, comprising:

a catheter having a proximal end portion and a distal end portion, the catheter defining a lumen extending through the proximal end portion and the distal end portion of the catheter;

an introducer defining an inner volume, the introducer having a distal end portion configured to be coupled to an indwelling peripheral intravenous line, the introducer configured to transition between a first configuration, in which a guide member is disposed within the introducer, and a second configuration, in which at least a distal end portion of the guide member is distal to the introducer and within the indwelling peripheral intravenous line; and

an actuator coupled to the catheter and configured to transition the introducer between the first configuration and the second configuration, at least the distal end portion of the catheter being isolated within the guide member and moving with the guide member as the introducer is transitioned from the first configuration to the second configuration, the actuator configured to move the catheter relative to guide member when the introducer is in the second configuration such that the distal end portion of the catheter is distal to the guide member.

2 . The apparatus of claim 1 , wherein the guide member at least partially encloses at least the distal end portion of the catheter when the introducer is transitioned from the first configuration to the second configuration.

3 . The apparatus of claim 1 , wherein the guide member is disposed in a portion of the indwelling peripheral intravenous line when the introducer is in the second configuration, and

the guide member is disposed between an outer surface of at least the distal end portion of the catheter and an inner surface of the portion of the indwelling peripheral intravenous line prior to the catheter being moved relative to the guide member.

4 . The apparatus of claim 1 , wherein the actuator is maintained in a fixed position relative to a portion of the introducer when the actuator transitions the introducer from the first configuration to the second configuration.

5 . The apparatus of claim 1 , wherein the actuator is maintained in a fixed position relative to a portion of the introducer when the actuator transitions the introducer from the first configuration to the second configuration and the actuator is configured to move relative to the portion of the introducer to move the catheter relative to the guide member.

6 . The apparatus of claim 1 , wherein the guide member has a first stiffness and the catheter has a second stiffness less than the first stiffness.

7 . The apparatus of claim 1 , wherein a distal end surface of the guide member is configured to be disposed within the peripheral intravenous line when the introducer is in the second configuration, the actuator is configured to move the catheter relative to the guide member to place a distal end surface of the catheter outside of and distal to the peripheral intravenous line.
